The roll-out will be sequenced – according to Nokia’s CEO, the WP handsets will be available “in one country after another after another over time.”

Elop believes Nokia’s Windows handsets – which will run Mango – “will be very successful because of the unique capabilities that we’re bringing from Nokia, the quality of the design, the strength of our organization.”

Nokia hopes that lots of Symbian users will adopt Windows Phone, and the company is “doing some things to help a Symbian user move certain information” from a Symbian device to a new Nokia Windows device.
